Patent ed Nov. 21, 1933 UNITED STATES 'PfATENTTOFFICE SOLE REST'FORPULLING-OVER MACHINES Robert P. Frye, Marlboro, Mass. ApplicationJanuary 12, 1933. .Serial No. 651,272

1 Claim. (01. 12- 4) This invention relates to pulling-over machinesused in preparing-shoes for lasting by performing the operation ofpulling the upper over upon a last and an inner sole of a shoe when theshoe parts are assembled on the last, and particularly to a machinewhich includes pullingover mechanism organized as shown by the Mo- FeelyPatent No. 1,029,387, granted June 11, 1912.

The McFeely machine includes a shoe bottom rest called a sole rest,adapted to position the inner sole on the last with its toe end flushwith the toe end of the last, the rest being movable to move the innersole forwardly and backwardly on the last, and the shoe being presentedbottom upward to the sole rest and supported thereby while the upper isbeing pulled about the last.

A function of the sole rest is to conform the fore part of the innersole to the fore part of the last bottom. All portions of the margin ofthe inner sole fore part should be in close contact with the last bottomin order that there may be no gap between the inner sole and the lastbottom when the upper is being pulled over by the usual wipers. A gap atany point causes liabiiity of displacement of portions oi the upperlining in the form of folds or puckers which project between the innersole and the last bottom and remain there in the completed shoe, thusconstituting an imperfection in the shoe. Moreover, if the portions ofthe inner sole edge are separated by gaps from the last bottom, suchportions are liable to be distorted by pressure of the side wipersagainst them, so that burrs are formed on the sole edge constitutinganother imperfection.

The construction of the McFeely sole rest is such that the completedshoe is liable to have the above mentioned imperfections.

The object of my invention is to so improve the sole rest as to preventany liability of imperfections caused as above stated.

Of the accompanying drawing forming a part of this specification,-

Figure 1 is a longitudinal section through the sole rest mechanism of apulling-over machine showing my improved sole rest, the mechanism beingotherwise as shown by the McFeely patent.

Figure 2 shows in perspective my improved sole rest.

Figures 6 and 7 are views similar to Figures 1 and 3 showing the solerest of the McFeely patent.

Figure 8 is a section on line 8-8 of Figure 7:

The same reference characters indicate th same parts in all of thefigures.

The sole rest hereinafter described is associated, as described by theMcFeely patent, with means for pulling an upperover a last, and meansfor actuating the sole rest to move the inner sole with relation to thelast, the general operation of the sole rest being as fully set forth bysaid patent. 7

To facilitate an understanding of the'nature and object of my invention,I will first describe the sole rest of the McFeely patent.

The sole rest is mounted slidingly in a carrier 120 which is pivotallysupported. The sole rest comprises a shank 118, having two arms 124which extend obliquely forward from the shank to engage the rear portionof the fore part of the inner sole S near its opposite edges, and'a'narm 126 which extends directly forward toward the toe of the inner sole,as shown by Figure 7. The arm '126 has an adjustable foot piece 127pivoted to it at 128, and acted on by a spring-pressed plunger 130. Thefoot piece is provided with a stop screw 132 for adjusting it about itspivot to vary the vertical position of the acting end of the foot piecewith relation to the arm 126, so that the sole rest may be adapted toproperly engage lasts, the bottom faces of which have diiferent degreesof curvature.

The adjustable foot piece 127 projects forward from the arm 126, and itsforward end engages the toe portion of the inner sole S only on thelongitudinal median line thereof as indicated by Figure 7, so that thefoot piece 127 does not engage the toe portion of the inner sole in suchmanner as to press the entire edge of-the toe portion against the curvedbottom of the last; In other Words, the median line of the toe portioncontacts with the sole bottom, and the edges of the toe portion atopposite sides of the median line stand out from the last bottom so thatthe gaps shown by Figure 8 are formed.

The mechanism shown by the McFeely patent for wiping and pressing thepulled upper into position to receive tacks securing the upper to theinner sole and last includes wipers 6i) which are movable to wipe theedge of the upper over upon the outer side of the inner sole and areadapted to exe"t pressure on the wiped over edge and hold it fromslipping back afterit is released by the grippers 186. Two of the wipers60 are shown by Figure 4, and one by Figure 8, the wipers being shown intheir outward position before they are actuated to perform their funcntion. These wipers are movable crosswise of the last, and are called thelateral wipers.

After the lateral gripper carriers 161 (Figure 5), are actuated to causethe grippers 186 to pull over the upper, the lateral wipers are actuatedinwardly to hold the upper preparatory to tacking the upper to theinsole and last.

By reference to Figure 8 it will be seen that when there are gapsbetween the inner sole edge and the lastcbottom, the lateral wipers 60in moving inwardly from the position shown to perform this function, areliable to press the edge of the upper inwardly against the edge.portions of the inner sole which stand out from the last bottom, beforesaid edge portions are forced downwardly against the last bottom by theactuation of the lateral wipers. The edges of the inner sole aretherefore liable while they are being forced downwardly, to displaceportions of the upper lining in such manner as to cause wrinkles orpuckers on the lining which project into the gaps between the inner soleand the last bottom, and are pinched and permanently retained thereinwhen the gaps are closed, thereby causing an objectionable defect.

It sometimes happens that when the margin of the toe portion of theinner sole stands out from the last bottom the lateral wipers 60 exertpressure on the edge of the standing out portion of the sole edge, saidedge being usually relatively thin and known as the insole feather. Suchpressure tends to crush the innersole edge and form burrs thereon whichcause irregularities on the outer side of the upper which are noticeablein the completed shoe, and constitute another defect.

In carrying out my invention I substitute for the adjustable foot piece127, the foot piece shown by Figures 1, 2, 3, 4, and 5. This foot pieceincludes a shank 12 pivoted at 13 to the arm 126,

and in alignment with the shank 118, and two arms 14 projectinglaterally from the shank and arranged to bear on the margin of the toeportion of the inner sole S at opposite sides of the longitudinal medianline of the sole, as indicated by Figures 3. The arms 14 may projectobliquely forward as shown by Figures 2 and 3, or they may be in linewith each other and project laterally without projecting obliquelyforward, the shank l2 and arms 14 forming a T-shaped body. The footpiece formed by the shank l2 and arms 14 is adjustable, like the footpiece 127, about the pivot 13 to vary the vertical position of theacting ends of the arms with relation to the arm 126. The feet, oracting portions of the arms 14, are preferably formed by flanges 16formed and arranged to bear on the margin of the toe portion of theinner sole and press said margin against the last bottom, as indicatedby Figure 4, so that no portions of said margin stand out from the lastbottom, and there is no liability of pinching portions cfthe liningbetween the inner sole and the last bottom, and of crushing the marginof the toe portion of the inner sole bythe lateral wipers 60.

The wiper 60 shown by Figure 1 is movable lengthwise of the last, and isnot a lateral wiper, its function being to act on the middle of the toeportion of the upper.

I claim:

A pulling-over machine sole rest including laterally extending arms forengaging the rear portion of an inner sole fore part near its oppo--site edges, and'a forwardly extending arm, said rest being characterizedby a foot piece, adjustably connected with, said arm, and havinglaterally extending arms for engaging the toe portion of said fore partat opposite sides of the. longitudinal median line of the inner sole.
